Over the past few decades, the shape of the delta has changed significantly, as ocean waves have carved away at the coastline, submerging and shrinking habitats.http://phys.org/news/2015-07-river-deltas.html

Environment Tue, 02 Jun 2015 15:40:01 EDTnews352477529Researchers to put cutting edge wave power technology to the test in real ocean conditionsOceans – which after all cover some 71 % of the earth's surface – represent an untapped source of clean, renewable energy. Early demonstrations have already shown that the energy stored in waves can be captured by floating energy converters. Now scientists want to rigorously test this technology on a much larger scale, to see whether the concept is truly viable and whether hardware is capable of surviving rough sea conditions over a period of several years.http://phys.org/news/2015-05-edge-power-technology-real-ocean.html

Energy & Green Tech Tue, 10 Feb 2015 09:50:04 EDTnews342781404Study examines role of acoustic-gravity waves as ocean transport, early warning of tsunamisAcoustic-gravity waves—a special type of sound wave that can cut through the deep ocean at the speed of sound—can be generated by underwater earthquakes, explosions, and landslides, as well as by surface waves and meteorites. A single one of these waves can stretch tens or hundreds of kilometers, and travel at depths of hundreds or thousands of meters below the ocean surface, transferring energy from the upper surface to the seafloor, and across the oceans. Acoustic-gravity waves often precede a tsunami or rogue wave—either of which can be devastating.http://phys.org/news/2015-02-role-acoustic-gravity-ocean-early-tsunamis.html

Environment Thu, 21 Aug 2014 14:20:01 EDTnews327848647Huge waves measured for first time in Arctic OceanAs the climate warms and sea ice retreats, the North is changing. An ice-covered expanse now has a season of increasingly open water which is predicted to extend across the whole Arctic Ocean before the middle of this century. Storms thus have the potential to create Arctic swell – huge waves that could add a new and unpredictable element to the region. A University of Washington researcher made the first study of waves in the middle of the Arctic Ocean, and detected house-sized waves during a September 2012 storm. The results were recently published in Geophysical Research Letters.http://phys.org/news/2014-07-huge-arctic-ocean.html
